When I click on an email in my mail 'inbox', items open in a 'send' window? Why don't they open into a 'read' window? Why are emails opened with red outline boxes and largely inaccessible? Can you help? Must I reload Thunderbird and Firefox? Are there tweaks that I am missing. I have spent several hours trying to sort this out, so far no luck!! Can you help?

I would like to disable automatic session restore completely. When I restart my PC, crashes or anything like that, I do not want Firefox to restore my previously opened tabs or windows. When I open firefox after a system reboot / crash, I want to only open my default home page. Only if I manually click History > Restore Previous Session should firefox ever restore my session, otherwise never restore my sessions.

I tried unchecking Settings > Startup > Open previous windows and tabs, and also tried following this article: https://support.mozilla.org/en-US/questions/1182594

My sessions still restores after my computer restarts or crashes.

Why do I want this? When I reboot my computer, I want a clean slate to start from scratch, not the dozens of pages (and other software) I had open from my previous session.

I am running linux mint btw.

The city that comes up on the 'weather' icon is wrong. I try to change it by following the instructions, but there is no drop down menu after I put in the correct zip code. There is no movement at all if I hit Enter or any other key. Please advise.

My Mozilla Firefox bookmarks are Bookmarks 2025-07-22.JSON. They worked well on my older Dell computer. I bought a new Dell desktop computer. I am disgusted with Google. My bookmarks on my C Drive. If you can't help me reload those bookmarks, I may as well decide to delete Firefox and use another such as Total Browser. I certainly hope you will help me load 2025-07-22.JSON on my new computer - it is ridiculous that Firefox wants to put in the full address on the C Drive instead of simply loading those. On Firefox on my last computer I used News which was bookmarked Daily Wire, Epoch Times, Salem News Channel, God's World News, One America News, Washington Times, New York Sun, and local Sterling Virginia Weather. I also use biography sites https://www.Worldhistory.org and Britannica.com [both of which I pay for monthly, as https://www.wikipedia.org/. I also have a Biography folder with names from A to Z I also have many music folders 1940s, 1950s, 1960s, 1970s, 1980s, 1990's, 2000s, Music group and singers A to Z, Blues music, Bluegrass, Christian Alternative Music, Country classic, Country & Western Gospel, Folk Singers, Jazz, Motown, Soul and many others which I have gathered over the past 10 years

How specifically do I stop the current version of Firefox for Android from automatically refreshing its self without me specifically refreshing it? This is such a widespread nuisance for people, why can you guys not fix this?

I'm running Windows 10 and recently switched from the ESR Channel version (128.11.1) to the Release Channel version (139.0.2) and, since then, have started having a problem where the unread email count displayed on the system tray icon and also the count on the Taskbar icon are no longer correct. Most incoming, unread emails aren't counted. This feature has always worked correctly for me previously, ever since I first installed Thunderbird several years ago. When I go into Thunderbird, the count of unread emails in whatever folder they're in is still correct, the problem is just with the counts on the taskbar and tray icons.

I'm not 100% sure, but I *think* it might be the case that emails which end up in the default "Inbox" folder are added to the counts, but those which are automatically allocated on arrival to other folders on the basis of filter rules aren't being added to the counts displayed on the icons. I have searched for others reporting the same issue and haven't been able to find anything, so it seems unlikely that it's a bug. I'd greatly appreciate any help in resolving this issue please.

Ive been using firefox for a while and i heard that you guys send out stickers and id love to aquire a couple stickers to put on my locker, thank you for your time.

Good day,

The old version of Firefox prior to July 26, 2025 opened multiple browsing tabs. These tabs looked like the ones from my toolbar.

When I uninstalled Firefox after July26, 2025 and reinstalled it I opened and still all of the tabs would open again.

I tried to delete the history and still the tabs opened. I refreshed and reset and still the tabs opened.

I do not want to lose saved history or have to delete multiple tabs every time I open the browser.
Thank you

I do habe a description, hoffe to aktivste JavaScript, but I Canterbury find Outlook how to get to "about:config" to choose "Javascript enabled" in order to Check if JavaScript ist aktivsten there. Does anyone know, how I get to the configeration-editor "about:config"?

I am trying to enable GPC on my phone as I have been having problems for a long time. When I type it into the address bar, nothing happens.So unable to choose the preference I require. Thank you

I have a yahoo email account that forwards emails to Thunderbird. One person I receive emails from uses Fastmail. Messages from Fastmail often have a portion of the email that has super large fonts. The messages look normal on the yahoo web mail site, but have super big fonts in Thunderbird. If I cut and past the portions with big fonts into my word processor, the fonts look normal as well. I clipped a portion of the html from one of these emails (attached) and you can see from the "font-size" values why the size is so large with values like "8889%" versus "18px". I have no idea where the bogus values are coming from (i.e. Fastmail, yahoo, Thunderbird). But apparently Thunderbird scales the fonts up where the web browser and my word processor seem to ignore the bogus values. Thanks in advance.

Im trying to watch a video and im only getting this message telling me to enable Javascript in my browser settings, How in Gods name is this accomplished

 Thank you for any help you can provide

It seems that Javascript might not be enabled in Firefox on Android. I've seen old answers advising going to about:config, but there is no such target anymore. All that typing that in does is search for about:config. That's obviously not very useful.

See the image below, how do I prevent that black box showing up and showing anyone who uses my device my sensitive data? How is this not a common setting to be changed?

Very insecure and Horrible to have on by default. Recently switched to firefox from chrome because of security concerns but stuff like this is making me want to go back, because HOW IS THIS SAFE AND SECURE?!?!?!?

I've typed in passwords in boxes that arent really password boxes, and firefox has suggested my own password in plain sight like in the image below.

Strongly recommend firefox to not make this default and make it an accessible setting to disable because I've leaked my sensitive information to online calls because of this. This urgently needs to be addressed as a security concern. At least have a cogwheel button next to the black box to quickly disable this setting. Very very disappointed.
